              "equivalence": "narrower",
              "comment": "The source code does not necessarily mean that the patient has moved to an inpatient visit"
            }
          ]
        }
      ]
    }
  ]
}
On /fhir/r5/ and /fhir/r6/, target entries use the FHIR R5 relationship code (e.g. source-is-broader-than-target) instead of R4 equivalence. Source codes the IG leaves unmapped appear as target-less elements.
An unknown id returns a 404 OperationOutcome.
